The line to West Valley is used occasionally for secretive shipments out that contain low level nuclear waste - these trips usually occur in the middle of the night for obvious reasons. The federal government provided funds to the B&P to rehab the line to the West Valley nuclear site, and also on the main line to its connection to NS at Machias Jct. Yes, ties have been placed all along the line for replacement. As far as the hoppers between Great Valley and Salamanca, these are on a siding owned by Gernatt Gravel & Asphalt Products, and an old B&P GP-9 is used to shuffle the cars under the loader. I believe this loco is now owned by Gernatt, as it has their name painted under the cab window. I was told this siding was also to be available for other customers as a team track, but there usually isn't any room for any other cars, and I haven't seen anything different than the old hoppers there. The railroad uses part of the old wye at the depot in Salamanca for a team track as well, and there are often log cars spotted there and logs are loaded on these for out shipments. I believe occasional interchange takes place between B&P and the WNY&PA at the Windfall connecting track. As far as mainline trains, there are usually only two per day, one early AM between 6 and 7 AM through Ellicottville/Great Valley, and the opposite counterpart around 10 PM in this area. Trains aren't overly long either, usually 30 to 40 cars, although they often have 3-4 locos, usually the SD-45's and lately a way cool old SP tunnel motor lettered LTEX (Larry's Truck & Electric, I think). I've got to get a photo of that one before it leaves the property. These trains may pick up additional loads at Bradford on their way south, so maybe this is why they have the extra power on. Trains can often be found tied up at the East Salamanca depot in the evening and on weekends.
